“To the 'Bar X' on the Canadian. I've worked with that outfit. They'll give us whatever we need, and ask no questions; I don't know of anything in between. It's going to be a hard ride, boy, and mighty little to eat except what I saved from supper.” “How far am it to dis yere 'Bar X'?” “A hundred and fifty miles as the crow flies, and sand all the way, except for the valley of Salt Fork. Come on now, and keep close, for it's easy to get lost in these sand hills.” Keith had ridden that hundred and fifty miles of sandy desolation before, but had never been called upon to make such a journey as this proved to be. He knew there was little to fear from human enemies, for they were riding far enough east of the Santa Fé trail to be out of the path of raiding parties, while this desert country was shunned by Indian hunters. It consisted of sand hill after sand hill, a drear waterless waste where nothing grew, and amid the dread sameness of which a traveller could only find passage by the guidance of stars at night or the blazing sun by day.

Keith, all sense of direction long since lost, rolled wearily from the saddle, burrowed under the partial shelter of a sand dune, and called upon Neb to follow him. With their hands and feet they made a slight wind-break, dragging the struggling ponies into its protection, and burrowed themselves there, the clouds of sand skurrying over them so thick as
